Represent Data in Circle with Colormap

I have a set of data in a 1x48 array. This data represents temperature values of radial slices of a circle (Basically the temperatures of 48 slices of pie around the same pie). I need to find a way to translate those temperature values from the array into a circular plot that would represent a temperature profile of sorts. So far, I have found the following color wheel code that is close to what I desire, with the large exception of not being able to input data:

N = 48;

c = colormap(jet(48));

th = linspace(0, 2*pi, N);

r = 0.5:0.5:1;

[TH,R] = meshgrid(th,r);

[X,Y] = pol2cart(TH,R);

C = bsxfun(@times,(X + Y),th);

figure(1)

surf(X,Y,C)

view([0 90])

axis square

grid off

This code produces the base shape for what I need to achieve, but I need the colormap to represent data that I can input, instead of just arbitrary values. It would be ideal to assign the selected data to each of the "pie slices" created by the linspace function, but I can't seem to figure it out. Thank you in advance.

You can define your own colormap or you can use predefined colormaps too

colormap jet(15)   %if you want 15 colors on the colorbar
colormap cool(20)   %20 colors on the colorbar

Define your own colormap:

CC=[238,233,233;216,192,216;255,193,193;238,106,167;205,0,205;...
    138,43,226;131,111,255;30,144,255;...
    0,238,118;69,139,0;...
    238,118,0;255,0,0]
colormap(CC/255)
colorbar
